Question

我正在尝试从SQLLite数据库中捕获值并将其显示在列表视图中。

我完成了编码，但我的代码中没有发现错误，但在执行后，列表视图中没有显示任何内容。

任何人都可以帮我解决这个问题。

这是我的代码。

Answer 1

更改为

 public void Temple_Adapter_Adapter(Contextact, int layoutResourceId,
                            ArrayList<kovil> data) {
  super(act,layoutResourceId,data);
                            this.layoutResourceId = layoutResourceId;
                            this.activity = act;
                            this.data = data;
                        }

你也忘了在这里传递arraylist

   tAdapter = new Temple_Adapter(MainActivity.this, R.layout.activity_main,temple_data);

并删除

      public Temple_Adapter(Context context,
                            int textViewResourceId) {
                        super(context, textViewResourceId);
                        // TODO Auto-generated constructor stub
                    }

您还没有覆盖getView。建议将适配器移动到单独的.java文件

 public View getView(int position, View convertView, ViewGroup parent) { 
     ViewHolder holder; 

     if (convertView == null) { 
         convertView = mInflater.inflate(R.layout.layoutResourceId, 
                 parent, false);
         holder = new ViewHolder(); 
         holder.tv1 = (TextView) convertView.findViewById(R.id.textView1)
         convertView.setTag(holder);  // set tag on view
    } else { 
        holder = (ViewHolder) convertView.getTag();
    } 

    holder.tv1.setText(data.get(position).temple_name);
    return convertView; 
 }
static class ViewHolder
{
     TextView tv;
}

我遇到了同样的问题，通过询问2个问题解决了问题。
